To all whom, it may concern:

Be it known that I, CARL BARTELS, a c1t1- zen of the United States, residing at Hamilton, Butler county, Ohio, have invented cer-' tain new and useful Improvements .m Safe or Vault Walls,0f which the following is.

a specification.

This invention pertains to. improvements.

' which r r wall-plates: 2, the adjoining so Figure 1 is a perspective view of portions of two abutting wall-plateswhosejolnt of union is secured by an embodiment of my improved system: Fig. 2 a'horizontal section of the same in the plane of hue a of Figs. 1 and 3: Fig. 3 a vertical section 1n the plane of line b of Flgs. 1, 2 and 4E: and Fig. 4 an inner elevation of one of the clamps. v

In the drawingz' 1,. indicates one of the wall-plate: 3, p ates, the edges being illustrated this form of joint-surface being the joint between the two of the plates at this joint as plain,

1 preferably with plates of unmachinable metal as it permits of the contacting surfaces being satisfactorily formed by grinding operations: 4, studs integrally formed with the plates and projecting from the inner surface t ereof near the joint between the plates: 5, atbar. of machinable metal Se cured to the inner surface of plate 2 by having studs 4 pass through holes in the bars and riveted therein: 6, a si ilar bar similarly secured to the inner sur ace at the joint edge of plate 1: 7, the joirib between the inner edges of-the two bars, (it being preferable that the bar upon one plate overlap the other plate and that the inner edge of one bar engage to the rear of the inner edge of the other bar so that, so to speak, one bar hooks in behind the other bar; 8, dovetail edges formed on the outer edges of the two bars, these outer edges being of tapering character along the length of the bars so that, conjointly considered, the two bars are wider at one end than at the other: 9, clamp-blocks having their inner surfaces grooved and dovetailed properly fit upon the wide and clamp-blocks but it is V sumed that the accessible so that the clamp-blocks could, in

to'- fit the exterior edges of the bars: 10, notches or cutaway portions in the dovetails at the outer edges of the bars: and. 11, notches or cutaway portions at the dovetails of the clamp-blocks.

The plates 1 and Zand the bars having been properly formed, andthe bars having been properly secured to the plates-in the manner ex lained, and the two plates with their bars having been properly associated, one of the clamp-blocks is slipped over the end of the bars and passed down to desired position upon the bars, say at the lower ends of. the bars, and a driven tight, this clamps the two plates solidly endwise together at the point of location of that particular clamp-block. A second clamp-block is then similarly applied and driven, and so on. for a series of clamp-blocks whereby the joint between the plates becomes firmly made throughout its number of the clamp-blocksyand the distance between the clamp-blocks of the series will depend upon the length of the joint between the plates and also upon the desire as to how close be in the completed structure. It is to be understood that as the exterior edges of the bars are tapering the width of the dovetailed grooves in the clamp-blocks will need to vary accordingly in order that they may narrow portions of the bars.

It has thus far been assumed that the bars are continuous bars receiving a-series of obvious that the bars may be discontinuous, the only necessity in this respect being that they shall furnish a proper seating for each of the clampblocks. The above description ,has also asnarrow ends of the bars were succession, he slipped 'over the ends-of the bars. But this cannot always be the case, for in vault construction the bars might extend from ceiling to floor, and in such case provision must be made for applying the clamp-blocks to the bars without the necessity for endwise application. The notches 10 in the bars are of such width as to ermit the entrance of the uncutaway portions of the dovetails of the clamp-blocks. This permits a given clamp-block to be presented against the face of the bars and then pushed down and driven to tightness. Where the together the clamp-blocks shall entire, length. The p clamp-blocks are presented to the ends of the bars, as in the manner first described, it must be done in a serial manner, that is to say, the clamp-block pertaining to the widest part of the bars must be first applied, and then the next, and so on, while when the notched system is employed the clamp-blocks may be applied in any order desired.

I claim 1. A safe or vault Wall comprising, Wall plates having their edges in contact, bars secured to the inner surface of said plates at the sides of the'joint and having dovetailed tapering edges, and a series of clampblocks disposed against the inner faces of said ,bars and engaging their outer edges, combined substantially as set forth.

2. A safe or vault Wall comprising, wall plates having their edges in contact, bars secured to the inner surface of said plates at abutting contact and having their inner surfaces provided with integrally formed studs near the joint between the edges of the plates, a bar of metal disposed at the inner surface at the edge of each plate and having their outer edges dovetailed and tapered and the bars being secured to the plates by means of said studs being riveted in holes in the bars, and clamp-blocks disposed across the inner face of said bars and'engaging the dovetailed tapering edges of the bars, combined substantially as set forth. I

4. A safe or vault wall comprising, plates of unmachinable metal having their edges in surface at the edge of each plate and having their outer edges dovetailed and tapered and the bars being secured to the plates by means of said studs being riveted in holes in the bars, and clamp-blocks disposed across the inner face of said bars and engaging the dovetail tapering edges of the bars the outer edges of the bars and the engaging surfaces of the clamp-blocks being notched to permit of the clamp-blocks being applied facewise to the bars, combined substantially'as set forth.
